The overall score for the AP Statistics exam is calculated on a scale from 1 to 5. A score of 3 or higher is considered for advanced placement and college credit. However, every college has a specific set of requirements regarding AP credit. Be sure to check with your college to learn about their AP credit policy and regulations.

Coming back to the AP Statistics exam structure, let's discuss each section in detail.

Section I

The first section consists of 40 multiple-choice questions. The total time allotted for this section is 1 hr 30 mins, which gives you roughly about two minutes to answer each question. You are allowed to use a graphing calculator for this section.

Section II

This section has two parts, Part A consists of five FRQs, and Part B includes one question, which is an investigative task. You will need to use a graphing calculator to approach this section. The table below breaks down Section II for an easy read:

Section II Part A Part B
Total Time Allotted 1 hr 30 mins 1 hr 30 mins
Calculator Usage Permitted Permitted
No. of Questions 5 1
Question Types 1. One multipart question with a primary focus on collecting data One investigative task that assesses multiple skill categories and content areas, focusing on applying skills and content in new contexts or non-routine ways
2. One multipart question with a primary focus on exploring data
3. One multipart question with a primary focus on probability and sampling distributions
4. One question with a primary focus on inference
5. One question that combines two or more skill categories

Now that you have a good grasp over the sections and number of questions on the AP Statistics exam let us dig deeper and learn what these questions will test you on.

Part A contains five short-answer questions. Each of these questions can include several parts. For Part A, it is ideal to answer each question in about 12 minutes each and keep about 30 minutes to complete the investigative task in Part B.

Part B contains the most in-depth question on the test, and you should answer it in about 30 minutes. It will have multiple parts that you must answer and will require a variety of statistics skills. You will also need to explain your answers to demonstrate your statistical knowledge. Your answer will be graded holistically, so make sure to show all the steps you took to deduce your answer.

Types of Questions in AP Statistics Exam

As mentioned earlier, each of the two sections in the AP Statistics exam carries 50% weight of the total exam score. Now let us discuss each section of the exam, including the units they cover from the AP statistics course and the weight each of these units carries. Although the College Board® does not specify the unit weights for the Free-Response section, we can find out the unit weights for the multiple-choice questions. We will also address a few tips on approaching these with ease.

Section I: Multiple Choice

As you may already know, the MCQ section includes 40 questions, each with five predetermined answer choices. For each question, you must select the correct answer from five options. These answer options are frequently similar, leading the student to believe that there could be more than one correct answer. Take your time to answer each question by taking a hint from the answer choices and pick the option that matches the derived answer.

The nine units that you will study during your AP Stats course will carry varying weights in the MCQ section. Let us look at these units and their respective weights in Section I.

Unit Weight in MCQ Section
Unit 1: Exploring One-Variable Data 15–23%
Unit 2: Exploring Two-Variable Data 5–7%
Unit 3: Collecting Data 12–15%
Unit 4: Probability, Random Variables, and Probability Distributions 10–20%
Unit 5: Sampling Distributions 7–12%
Unit 6: Inference for Categorical Data: Proportions 12–15%
Unit 7: Inference for Quantitative Data: Means 10–18%
Unit 8: Inference for Categorical Data: Chi-Square 2–5%
Unit 9: Inference for Quantitative Data: Slopes 2–5%

Remember that the units carrying higher weights will reappear more often in the MCQ section. For example, you will most likely get more questions from Unit 3 than from other units, like Unit 8. Keeping this in mind will help you focus on these sections, and you can distribute your study plan based on the unit weights.

Now let's move on to the Free-Response Section and learn more about it.

Section II: Free-Response

The free-response questions in Section II, require you to demonstrate the step-by-step processes you employed to solve a problem and derive the answers. As we have already discussed, this section assess your analytical and problem-solving skills. It is graded manually by AP instructors and college teachers called AP Readers. Both parts A and B in this section employ holistic marking, where you will be graded on how you approached the problem and derived the correct answer.

While you focus on learning how to answer AP Stats free-response questions, remember to take a few AP Statistics practice tests. It helps you boost your time management skills and familiarizes you with the question topics and patterns.
